Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0043] According to a first aspect of the present application, a cup holder device 10 is provided, which is suitable for use on a seat back 21 of a seat 100 with an adjustable unfolding angle, such as a conference seat, a cinema seat, an airplane seat, a vehicle seat, etc. For example, Figure 1 The figure shows the structure of the seat 100 to which the cup holder device 10 provided in the embodiment of the present application is applicable. Figure 1 This is a schematic structural diagram of the seat 100 provided in an embodiment of the present application. Figure 1 In the example shown, the seat 100 includes a seat 22 and a seat back 21 . The seat back 21 is adjustable in angle relative to the seat 22 , and the cup holder device 10 is disposed on the back of the seat back 21 .

[0044] The following combination Figures 1 to 10 , a detailed description of the cup holder device 10 according to an embodiment of the present application is given.

[0045] Reference Figures 1 to 4 The cup holder device 10 includes a mounting seat 11 , a cup holder 12 and a locking mechanism 13 .

[0046] The mounting seat 11 may be an independently provided mounting component, or the mounting seat 11 may be a part of the seat back 21 , that is, the mounting seat 11 and the seat back 21 are provided integrally.

[0047] The cup holder 12 is rotatably disposed on the mounting seat 11. For example, the cup holder 12 can be hinged to the mounting seat 11 via a hinge pin.

[0048] The locking mechanism 13 is used to lock the cup holder 12 relative to the mounting seat 11 to fix the expansion angle of the cup holder 12 relative to the mounting seat 11, or to unlock the cup holder 12 relative to the mounting seat 11 to adjust the expansion angle of the cup holder 12 relative to the mounting seat 11.

[0049] If the unfolding angle of the seat back 21 changes after adjustment while the unfolding angle of the cup holder 12 remains fixed, the cup holder 12 will tilt relative to the horizontal plane, causing the cup to lose stable support, which may cause liquid in the cup to spill or the cup to fall.

[0050] In the present application, the cup holder 12 is rotatably disposed on the mounting seat 11, and a locking mechanism 13 is provided. The locking mechanism 13 unlocks the cup holder 12 relative to the mounting seat 11. After unlocking, the unfolded angle of the cup holder 12 relative to the mounting seat 11 can be adjusted. The locking mechanism 13 locks the cup holder 12 relative to the mounting seat 11. After locking, the unfolded angle of the cup holder 12 relative to the mounting seat 11 is fixed, so that the unfolded angle of the cup holder 12 is adjustable. As a result, the cup holder 12 can be adjusted to a horizontal state to support the cup when the unfolded angle of the seat back 21 changes. This helps to reduce the problem of liquid spilling or cup falling caused by the cup holder tilting.

[0051] Reference Figure 9 In some embodiments, the supporting surface of the cup holder 12 is provided with a bracket 121. When the cup is placed on the cup holder 12, the bracket 121 can limit the horizontal movement of the cup, thereby helping to improve the stability of the cup.

[0052] In some embodiments, the bracket 121 is configured in an oval shape.

[0053] The cup holder 12 has different opening angles, and the relative position of the bottom of the cup and the supporting surface of the cup holder 12 is different. In this application, by configuring the cup holder 12 to be elliptical, the elliptical bracket 121 can position the cup when the cup holder 12 is opened at different angles.

[0054] In some embodiments, the locking mechanism 13 may be a ratchet mechanism (not shown), comprising a ratchet wheel and a pawl. The ratchet wheel is fixed to the cup holder 12, and the pawl is mounted on the mounting base 11. During use, the ratchet wheel and the pawl are unlocked to adjust the extended angle of the cup holder 12 relative to the mounting base 11. After the adjustment is completed, the ratchet wheel and the pawl are locked, securing the cup holder 12 to the mounting base 11, thereby fixing the extended angle of the cup holder 12.

[0055] Reference Figure 7 In other embodiments, the locking mechanism 13 includes a first locking member 131 and a second locking member 132 . The first locking member 131 is disposed on the mounting seat 11 , and the second locking member 132 is fixed to the cup holder 12 . The first locking member 131 is engaged with the second locking member 132 .

[0056] The locking mechanism 13 has a high degree of engagement stability. In this application, the cup holder 12 can be locked or unlocked from the mounting seat 11 by engaging the first locking member 131 with the second locking member 132. After the cup holder 12 is fixed to the mounting seat, the cup holder 12 is stably supported, thereby improving the load-bearing capacity of the cup holder 12.

[0057] For example, Figure 5As shown, in some embodiments, the first locking member 131 is a rack 131a, and the second locking member 132 is a gear 132a. The rotation axis of the gear 132a can be coaxial with the rotation axis of the cup holder 12. For example, the rack 131a can be flat, with the larger surface of the rack 131a being disposed on the teeth of the gear 132a. The gear 132a can be cylindrical, with teeth disposed on the circumferential surface of the gear 132a.

[0058] It should be understood that in other embodiments, the first locking member 131 and the second locking member 132 may both be gears.

[0059] Compared to the gear 132 a and the gear 132 a , the rack 131 a and the gear 132 a mate with each other in a smaller size, which helps to reduce the size of the cup holder device 10 and reduce space occupation.

[0060] Reference Figure 5 and Figure 3 In some embodiments, the mounting base 11 is provided with a slide groove 111 extending in a vertical direction, and the rack 131a is adjustably disposed in the slide groove 111 along the extension direction of the slide groove 111. It will be appreciated that when the cup holder 12 rotates, the rack 131a can move within the slide groove 111. When the cup holder 12 stops rotating, the rack 131a is fixed relative to the slide groove 111.

[0061] Since the gear 132a is fixed to the cup holder 12, when the expansion angle of the cup holder 12 is adjusted, the rotation of the cup holder 12 will drive the gear 132a to rotate synchronously, and the meshing position of the gear 132a and the rack 131a will change. In this application, the rack 131a can always be meshed with the gear 132a by moving along the slide groove 111, and the extension length of the slide groove 111 can control the movement stroke of the rack 131a, thereby controlling the maximum expansion angle of the cup holder 12. Specifically, Figure 5 and Figure 3 As shown, the chute 111 extends in the vertical direction, the rack 131a moves to the top of the chute 111, and the cup holder 12 is unfolded to the maximum angle. The rack 131a moves to the bottom of the chute 111, and the cup holder 12 is unfolded to the minimum angle, which can be 0°. It can be understood that the minimum angle means that the cup holder device 10 is in the retracted state.

[0062] In some embodiments, the rack 131a is slidably disposed in the slide groove 111. For example, Figure 7 and Figure 5 As shown, sliders may be provided at both ends of the rack 131 a , and the sliders are embedded in the sliding grooves 111 .

[0063] The locking mechanism 13 further includes a third locking member 133 disposed on the mounting base 11. The third locking member 133 is configured to lock or unlock the rack 131a in the slide slot 111. When the locking mechanism 13 is in the locked state, the rack 131a is locked in the slide slot 111. When the locking mechanism 13 is in the unlocked state, the rack 131a is able to move in the slide slot 111, thereby achieving adjustable position of the rack 131a in the slide slot 111.

[0064] In some embodiments, the third locking member 133 is configured to lock the rack 131 a in the sliding slot 111 or unlock the rack 131 a in the sliding slot 111 by pressing.

[0065] It should be understood that the pressing structure is easy to operate. In this application, by configuring the third locking member 133 to lock or unlock the rack 131a in the sliding groove 111 by pressing, the operation difficulty of the locking mechanism 13 is reduced, making it easier for users to operate.

[0066] Reference Figure 9 and Figure 7 In some embodiments, the third locking member 133 includes a base 1331, a pressing portion 1332, and a tooth portion 1333. The pressing portion 1332 is connected to one end of the base 1331, and the tooth portion 1333 is disposed on a side of the base 1331 facing the rack 131a. The tooth portion 1333 engages with the rack 131a. The pressing portion 1332 is configured to engage or disengage the tooth portion 1333 with the rack 131a by pressing.

[0067] In the present application, the pressing portion 1332 is used to drive the base portion 1331 to move, thereby driving the tooth portion 1333 to engage with or disengage from the rack 131 a , so that the rack 131 a is locked or unlocked in the sliding slot 111 .

[0068] Reference Figure 9 and Figure 10 In some embodiments, the locking mechanism 13 further includes a reset member 134 , which may be a spring, a spring, or the like.

[0069] One end of the reset member 134 is connected to the mounting seat 11, and the other end is connected to the pressing portion 1332. The reset member 134 is used to accumulate potential energy when the pressing portion 1332 is pressed, and drive the pressing portion 1332 to reset after the pressing portion 1332 is released.

[0070] During use, the user can press the pressing portion 1332 to disengage the third locking member 133 from the rack 131a. The rack 131a can then slide within the chute 111, unlocking the cup holder 12. In this unlocked state, the cup holder 12's unfolded angle can be adjusted. After the cup holder 12 is adjusted to a horizontal position, the user can release the pressing portion 1332, causing the reset member 134 to reset the pressing portion 1332. The third locking member 133 engages with the rack 131a, securing the rack 131a within the chute 111. The cup holder 12 is locked and secured in a horizontal position.

[0071] The present application sets a reset member 134 to drive the pressing portion 1332 to reset, so that the pressing portion 1332 can automatically reset after the user releases the pressure, without the need for manual reset, which helps to reduce the difficulty of operating the locking mechanism 13.

[0072] In some embodiments, the third locking member 133 further includes a connecting portion 1334 , the connecting portion 1334 connects the base 1331 and the pressing portion 1332 , and the restoring member 134 is sleeved on the connecting portion 1334 .

[0073] In the present application, the reset member 134 is sleeved on the connecting portion 1334 and the connecting portion 1334 is used to guide the reset member 134 , so that the reset member 134 is not easily twisted, which helps to improve the stability of the reset of the pressing portion 1332 .

[0074] In other embodiments, the rack 131a may not be provided. For example, the third locking member 133 may directly engage with the gear 132a (not shown). Specifically, the third locking member 133 includes a base 1331, a pressing portion 1332, and a tooth portion 1333. The pressing portion 1332 is connected to one end of the base 1331. The tooth portion 1333 is provided on the side of the base 1331 facing the rack 131a, and the tooth portion 1333 directly engages with the gear 132a. One end of the reset member 134 is connected to the mounting base 11, and the other end of the reset member 134 is connected to the pressing portion 1332.

[0075] In other embodiments, the locking mechanism 13 is locked or unlocked by rotation. For example, the locking mechanism 13 includes a knob, an elliptical cam, and a clamping member (not shown). The knob is used to drive the cylindrical cam to rotate. When the cam rotates until the flange contacts the clamping member, the clamping member presses against or clamps the second locking member 132. When the cam rotates until the flange separates from the clamping member, the clamping member releases the second locking member 132.

[0076] In some embodiments, the cup holder device 10 further includes a collar 14. When in use, the cup holder 12 supports the cup from the bottom, and the collar 14 secures the cup body of the cup so that the cup is not easily tilted when the seat 100 fluctuates.

[0077] The collar 14 is rotatably disposed on the mounting seat 11 and is spaced apart from the cup holder 12 in the bearing direction of the cup holder 12 .

[0078] For example, Figure 6 As shown, the collar 14 and the cup holder 12 can be spaced apart and parallel to each other. The rotation axis of the collar 14, the rotation axis of the cup holder 12, and the rotation axis of the gear 132a can be parallel.

[0079] In some embodiments, the cup holder device 10 further includes a linkage 15 , one end of which is movably connected to the collar 14 and the other end of which is movably connected to the cup holder 12 , and is configured to drive the collar 14 and the cup holder 12 to rotate synchronously.

[0080] The present application provides a linkage 15 to connect the sleeve 14 and the cup holder 12 , and utilizes the linkage 15 to link the cup holder 12 and the sleeve 14 , so that the sleeve 14 and the cup holder 12 are synchronously unfolded or folded for user convenience.
